I got a CEM SMD-100 Smart Electronic Components Tester because it was on sale at very low price. It turned out to be a bad investment. The component tweezers part make very intermittent contact with the meter, so measuring the components was very unreliable. The meter seemed to work OK with the measurement supplied leads →
http://www.worldwatch.org/node/4803 For the first time, scientists have produced a photovoltaic (PV) cell with a conversion efficiency of 40.7 percent, the U.S. Department of Energy (DOE) reported. The breakthrough cell was developed using a structure called a “multi-junction solar cell.” The technology may allow for lower PV system installation costs ($3 per watt) and lower electricity →

https://spectrum.ieee.org/semiconductors/devices/july-1958-kilby-conceives-the-integrated-circuit In 1958, 11 years after Bell Labs reinvented the transistor, it became clear that semiconductors would be able to conquer the electronics market only if they could be greatly miniaturized. In July1958, Jack S. Kilby of Texas Instruments came up with the monolithic idea. In January 1959, Robert Noyce was to jot in his →

We are in commercial 5G era! The world’s first commercial 5G networks were launched today in Tampere Finland and Tallinn Estonia. It was already expected that this year will see the first commercial rollouts of 5G networks. It seem that many telecom companies are aiming to launch 5G service really soon this year or next →
In January, at CES 2018, Wi-Fi Alliance announced that the WPA2 encryption used to protect Wi-Fi (WI-FI) since 2004 will get a new, more secure WPA3. Now standardization is complete and new devices that support wpa3 technology can be certified. The new protocol provides a number of additional protections for Wi-Fi enabled devices. WPA3 networks →
https://www.medengine.fi/en/almost-unstoppable-rise-finnish-health-tech/ The Finnish health technology field is booming like never before. In 2017, health tech exports broke new records as their value rose more than 5% to over €2.2 billion. The fact that the Finnish health tech field is thriving is hardly new: over the last two decades, the value of health tech export has →
